Referring more in detail to the drawings:

The reference numeral 1 generally designates a jogging machine having ajogging table structure 2 with a plura ity of table levels such as anupper table portion 3,

3,391,929 Patented July 9, 1968 a lower table portion 4, a sub-table 5,a base 6, and an extensible means 7 for elevating and lowering thejogging table structure 2 and the sub-table 5.

The jogging machine 1 includes a relatively rigid base 6 of suitablesize to provide a stable support for the machine, said base having aheavy plate-like member 8. In the structure illustrated there are aplurality of spaced adjustable base supports 9 with each consisting of afloor pad 10 connected to a screw shank 11, each of which is threadedinto a threaded bore 12 in the heavy plate-like member 8. The base 6 hasspaced upright guide members 13 such as tubular or sleeve memberssuitably secured to the base and which are illustrated as having flanges14 suitably fixed on the heavy plate-like member 8 by suitable fasteningdevices such as screws 15. The guide members 13 each have bores 16 forslidably receiving guide posts 17 as later described.

The sub-table 5 is maintained in vertical spaced relation to the base 6by elongate bars 18. The elongate bars 18 are held in selected relationand engagement with said sub-table 5 at their upper ends by suitablefastening devices such as clamping screws 9 with each having a slidablymounted handle, or lever 20, mounted in a head portion 21 and a threadedshank 22. The threaded shanks 22 of the clamping screws 19 are receivedin opposed threaded sockets 23 of the sub-table 5. The opposite or lowerends of the bars 18 are suitably connected to a beam 24 as by screws 25.In the illustrated structure the screws 25 have a head 26, washer 27,and a threaded shank 28. At opposed ends of beam 24 are flanges 29 whichhave threaded sockets 30 which receive the threaded shanks 28 of thescrews 25. Upper ends of the guide posts 17 are suitably connected tothe beam 24 as by welding.

The sub-table 5 is preferably of thick cast metal and of substantiallyrectangular form to provide a substantial rigid construction free fromany fiexure incidental to any vibration of the jogging table structure2. The opposite sides of the sub-table 5 are provided substantially onthe longitudinal median line thereon with the internally threadedsockets 23, which register with bores 31 in the bars 18 to receive thethreaded shanks 22 of the clamping screws 19 which form trunnions 32.The head portion 21 of the clamping screws 19 engages the outer face ofthe bars 18 and hold same in engagement with the side edges of thesub-table 5 whereby the sub-table 5 may rock or tilt relative ot thebars 18 but doesnot have lateral movement relative thereto.

The jogging table structure 2 at the lower table portion 4 includes arectangular frame 33 of connected members such as side bars 34 connectedby end bars 35 and suitably braced as by cross bars 36. Supporting theframe 33 is a sub-frame 37 which includes connected side bars 38 and endbars 39. The sub-frame 37 is supported in substantially parallelrelation to the sub-table 5 and in vertical spaced relation thereto. Thesub-frame 37 is movably supported from the sub-table 5 by spring leafconnectors 40. The spring leaf connectors 40 are connected to the sidebars 38 of the sub-frame 37 and to the sub-table 5 with suitablefastening devices such as screws 41.

The sub-table 5 and the jogging table structure 2 may be tilted about anaxis 42. The axis 42 is aligned with the median line of the sub-table 5which is defined by the trunnions 32. The threaded shank 22 of theclamping screw 19, the threaded sockets 23 of the sub-table 5, and thebore 31 in the bars 18 are aligned with the axis 42. When the clampingscrews 19 are loosened, the subtable 5 and the jogging table structure 2may be tilted to a selected position. The clamping screws 19 are thentightened to hold the sub-table 5 and the jogging table structure 2 inposition with the bars 18, the clamping screw head 21 and the sub-tablein clamping engagement. When the jogging table structure 2 and thesubtable 5 are tilted about the axis 42, a corner 43 of each of theupper table portion 3 and the lower table portion 4 is lower than anyother point on the respective table portion. The corner 43 has abisector which is substantially perpendicular to the axis 42.

The sub-table 5 is provided with a vertical bore 44, having anantifriction bearing 45 therein for rotatably mounting a shaft 46 whichextends vertically through the sub-table 5. The shaft 46 rotates aboutan axis that is essentially perpendicular to the sub-table 5. The shaft46 is preferably offset from the bisector of the corner 43 and issubstantially on the median line of the sub-table 5 as defined'by theaxis 42. A pulley 47 is fixed on the depending portion of the shaft 46and said pulley is driven by a belt 48 operating over a drive pulley 49mounted on a motor 50, said motor 50 being suspended below the sub-table5 by a bracket 51. An eccentric 52 is adjustably secured to the portionof the shaft 46 extending upwardly above the sub-table 5 whereby saideccentric 52 is rotated by the shaft 46 and operates an eccentric strap53 journaled on the eccentric 52.

Extending upwardly from the sub table 5 are spaced rocker arms 54journaled on stub shafts 55. The stub shafts 55 are preferably spaced onopposite sides of the axis 42 and in alignment with the bisector corner43. The eccentric strap 53 is connected to each of the rocker arms 54 bya spring leaf connector 56 with said spring leaf connector 56 beingconnected to the eccentric strap 53 and the rocker arms 54 by suitablefastening devices such as screws 57 at opposite ends of the spring leafconnectors 56. The rocker arms 54 are connected to brackets 58 by springleaf connectors 59 which are connected to said rocker arms 54 andbracket 58 by suitable fastening devices such as screws 60 at oppositeends of the spring leaf connector 59. The brackets 58 are connected tothe end bars 39 of the sub-frame 37 of the jogging table structure 2 bysuitable fastening devices such as screws 61.

Rotation of the eccentric 52 by actuation of the shaft 46 oscillates therocker arm 54 which oscillation is transmitted through the spring leaves59 to the jogging table structure 2 to effect vibration of the uppertable portion 3 and the lower table portion 4 of the jogging tablestructure 2.

The upper table portion 3 and the lower table portion 4 receive sheets62 of paper, or the like. The sheets 62 on the jogging table structure 2are caused to shift against and engage a guide or fence 63, at one sidewhen the table moves in one direction and then against the guide orfence 63 at the other side when the table moves in the oppositedirection resulting in the alignment of the guide engaging edges of thesheets 62. The arrangement of the leaf spring connectors 40 and thesub-table vibrating mechanism moves or vibrates the jogging table 2transversely of a plane bisecting the corner 43 therefore, the movementof the sheets 62 is laterally to alternately engage opposite guides orfences 63, and when the table is tilted to lower the corner 43 thevibration of the table will cause gradual downward movement of thesheets 62 until adjacent edges thereof are engaged by the guides orfences 63, which form an angular corner pocket wherein the sheets areretained in engagement with the guides or fences 63 and do not becomedisarranged because of continued vibration.

The extensible means 7 which rapidly elevates and lowers the joggingtable structure 2 to preselected levels includes a ram 64. In theillustrated structure the ram 64 includes a piston cvylinder structurehaving a piston rod 65 which has one end connected to the beam 24 as forexample and is located at an intersection of the axis 42 and thebisector of the corner 43. The piston rod 65 and piston thereof operatesin a fluid cylinder 66. In the illustrated structure the ram 64 iscontrolled by a valve 67 preferably of a conventional plunger four wayvalve structure, having a power source 68 and a fluid source 69. Thecylinder 66 and the valve 67 are connected by upper and lower fluidlines 70 and 71 respectively. The cylinder 66 is suitably supported onthe base 6 as by a flange 72 and suitable fastening devices such asscrews 73. In the structure illustrated the ram 64 is actuated to changethe height of the beam 24, the sub-table 5, and the jogging tablestructure 2 by operation of the valve 67. A counter (not shown), at apredetermined count activates the valve 67 by a signal and whereby thefluid pressure source forces fluid under pressure through one of thefluid lines 70 and 71 to the cylinder 66 where fluid is supplied to Onechamber in the cylinder 66, said valve bleeding fluid from the otherchamber of cylinder 66. When another signal is received from the counter(not shown) the valve 67 reverses and supplies fluid through the otherof the fluid lines 70 and 71 to the cylinder 66. Change in amount offluid in the chambers of the cylinder 66 elevates and lowers the piston65. Limit switches (not shown) may be installed at any desired elevationto control the distance of travel of the piston 65.

The height of the jogging table structure 2 may be adjusted verticallyfor proper height relative to apparatus from which sheets are to bereceived by adjustment of the bars 18. Each of the bars 18 has avertical slotted opening 74 through which the screws 25 are inserted.When the screws 25 are not fully tightened the jogging table structure 2and the sub-table 5 may be adjusted vertically in the plane of theslotted openings 74. When the table is in desired position the screws 25are fully tightened and there is a clamping engagement between thewashers 27, the bars 18 and the flanges 29 of the beam 24. The height ofthe jogging table is determined by the height of the delivery apparatussuch as a conveyor 75.

The guide posts 17 slide vertically within the guide members 13 tomaintain the bars 18 and the slotted openings 74 therein in asubstantially vertical plane. The piston rod 65 of the :ram 64 elevatesthe beam 24 which elevates the bars 18. The bars 18 thereby elevate thesubtable 5 and the jogging table structure 2 in a substantially verticalplane. During lowering of the piston rod 65 the bars 18, the beam 24 andguide posts 17 lower in a substantially vertical plane.

It is desirable that a power source 76 and a switch 77 which operatesthe motor 50 be independent of the power source 68 which operates thevalve 67 and the limit switches (not shown). In the structureillustrated the switch 77 is mounted on the opposite face of the motorsupport bracket 51.

When the jogging machine is in position the whole structure is leveledby the adjustable base supports 9. The piston rod 65 of the ram 64 ismoved to its bottom position so that beam 24 is at its lowest possibleelevation and the table is then adjusted in height in relation to thedelivery apparatus such as by means of the conveyor 75. When the tableis at the selected height the screws 25 are tightened to provideclamping engagement between the washers 27, the bars 18 and the opposedflanges 29 of the beam 24. The table is then tilted about the axis 42 toa selected angle and the clamping screws 19 are tightened to provideclamping engagement between the clamping screw heads 21 the bars 18 andthe sub-table 5. The motor is then turned on by switch 77 to vibrate thejogging table structure 2.

Sheets 62 are delivered by the conveyor to the upper table portion 3 andwhen a predetermined number of sheets 62 are delivered to the uppertable portion 3 a counter (not shown) activates the valve 67 by asignal. The valve 67 by supplying fluid to one opposed chamber andbleeding fluid from another opposed chamber of the cylinder 66 elevatesthe ram piston 65. The piston rod 65 continues to elevate until engagedby a limit switch (not shown), the limit switch stops the jogging tablestructure 2 at a preselected elevation so that sheets 62 may be receivedon the lower table portion 4. With the jogging table structure 2 in theelevated position the conveyor 75 delivers sheets 62 to the lower tableportion 4, a counter then activates the valve 67 by a signal at apredetermined number and the table is lowered until the table positionis reversed, or by lowering, the table is in the prior position. Whilethe table is in its lowered position jogged stacks of sheets 62 areremoved from the lower table portion 4 and when the table is in itselevated position jogged stacks of sheets 62 are removed from the uppertable portion 3. Thus, allowing a relatively continuous operation of thejogging machine and a fuller utilization of labor.
